Develop Reference

because flutter_app depends on both zego_uikit_prebuilt_live_audio_room ^1.0.7 and server any, version solving failed

I would like to develop a server that let clients can communicate with each other in the Server. When I add server to dependecies, here is the error.
Error Message:
Because every version of server depends on http ^0.11.3+16 and every version of zego_uikit_prebuilt_live_audio_room depends on http ^0.13.4, server is incompatible with zego_uikit_prebuilt_live_audio_room.
So, because flutter_app depends on both zego_uikit_prebuilt_live_audio_room ^1.0.7 and server any, version solving failed.

How can I solve the problem?
Thanks a lot.

Running Gradle task 'assembleDebug'. (This is taking an unexpectedly long time.)

when I created a very basic flutter app and ran it for the first time, it works perfectly, and when I try to add some dependencies in my pubspec.yaml file I get no errors in my project but when I run the app by 'flutter run' I get stuck in
Running Gradle task 'assembleDebug'...

and the app has never worked
this is my pubspec.yaml file
name: myPDFApp

publish_to: 'none'
version: 1.0.0+1
environment:
sdk: ">=2.7.0 <3.0.0"

Add an earlier version of the dependencies, and run pub get. This could solve the issue

Can't run the flutter app after added firebase-core and auth to the project

Here's the error in console, plus flutter doctor didn't showed any error. I've tried upgraded the android sdk to 28, check build.gradle. It still don't work and I have no clue.

1- Move them to dependencies
2- Leave a space at the beggining of the dependencie name like so:
dependencies:
flutter:
sdk: flutter
firebase_core: ^0.5.1
firebase_auth: ^0.18.2
google_fonts: ^1.1.0
provider: ^4.3.2+2
If you realize, it's like if flutter and the rest of your dependencies were at the same level

Its AAPT issue;
Open this open C:\Users\user\Desktop\Projects\Flutter\eLesson\android\app\src\main\AndroidManifest.xml and remove style/Theme.AppCompat.Light.NoActionBar
and
your App or some of you plugin is not compatible to AndroidX. Open android folder of your project in separate Android Studio. Right click on Project->Refactor->Migrate to AndroidX.
Repeat this process for each of your plugin folder.
Clean and Rebuild.
Enjoy.

why http.dart file shows empty when redirecting from import line after adding dependency , also http.get(url) method is undfined

i am a newbie in flutter, actually i am importing http.dart file after adding dependency "http: ^0.12.0" in pubspec.yaml , but as soon as i started importing http.dart file in main.dart and redirect to http.dart file , it shows empty there also the http.get(url) is unrecognized.
thats how i am importing http.dart file :-
import 'package:flutter/http/http.dart' as http;
and this is my pubspec.yaml:-
---
cupertino_icons: ^0.1.2
dependencies:
flutter:
sdk: flutter
description: "A new Flutter application."
dev_dependencies:
flutter_test:
sdk: flutter
environment:
sdk: ">=2.0.0-dev.68.0 <3.0.0"
flutter:
uses-material-design: true
name: flutter_app
shared_preferences: ^0.2.0
version: 1.0.0+1
any help would be appreciated, thanks in advance!

This is how you should import
import 'package:http/http.dart' as http;
This is how your pubspec.yaml be:
dependencies:
flutter:
sdk: flutter
http: any
Run $flutter upgrade to get latest flutter sdk

rxdart usage in Flutter not being recognized

I am trying to use rxdart package for the first time in my Flutter app and I have added the package in yaml file, then I saved it and vscode automatically ran flutter packages get on project after that complete I tried to import the package with following line
import 'package:rxdart/rxdart.dart';
but the compiler doesn't recognize rxdart within the packages. which is causing the error in the app.
The following are my dependencies of pubspec.yaml
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
rxdart: ^0.18.0
dev_dependencies:
flutter_test:
sdk: flutter
Update
Here is the repo for the project I am working on: https://www.github.com/touseefbsb/LoginStateful
You have to open the folder login_stateful_bloc and the error is in bloc.dart file where I am trying to import it.

You have to keep the indents :
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
rxdart: ^0.18.0

I was having the same issue. Even after pub get, it didn't work. Then I simply restarted my IDE(Android Studio) and now it works.

this worked for me, make sure you putted the dependencies on
dependencies:
flutter:
not
dev_dependencies:
flutter_test:
if that make sense :/
